And you will, in all likelihood, get your wish.
Disney is going gangbusters on Star Wars. Three sequels, plus at least two spin-off films . . . six Star Wars films have been made, Disney will probably double that number in the ten years following 2015. Yes, there will be merchandizing, (billions of dollars), and of course the money from the films themselves, but they are planting the seeds for a massive fan base.
And one thing fans like to do is go to conventions. It makes financial sense to build a Star Wars land (in a fifth gate) at WDW as they could bundle exclusive access to Star Wars land during a Star Wars celebration week/weeks at the resort. That is what makes money, filling hotel rooms and getting guests in the habit of migrating to WDW every couple years, and having special offerings where they could charge more, such as holding conventions on the property and bundling theme park admissions and convention admission.
They'll probably put in a fifth gate near the TTC, and they could call it a "Disney Adventure" park, with an emphasis on interactive experiences, and put NextGen twist on Carsland, Star Wars, some Pixar property . . . maybe even put in a 20K Under the Sea ride.
